Two previous attempts failed: one due to weather (see my trip report), the other due to taking a really long and inefficient route and getting burned out (settled for Bighorn Peak that day instead).
This time did it from Bells Canyon as a snow climb up the west gully to the north ridge, looping back into the gully via the south ridge, with vanman798, and it went perfectly, other than, thanks to the dark and my sleep deprivation for the alpine start, bringing an old right boot instead of my good left boot to the trailhead and having to go home to get it (after deciding that 6000 vertical feet would be hard in two right boots), delaying our start an hour, along with losing my GPS somewhere near the summit.

eight times to the Summit to date Across Thunder bowl, From South Thunder via the Ridge and Via Coalpit, I believe PellicidWombats first entry was one I lead for the WMC in 2004. Contrary to what Steve Elmer said in his entry we got chased a little by a Thunder storm while traversing the bowl that day.

Climbed via Coalpit with Steve Bohman and Grizz (MT RUNR). Coalpit was amazing, although it was pretty rough. I got a nasty gash on my arm from a sharp log and took a fall on a wet rock. Above the pit I hit the wall and the rest of the hike was hell. Only 14 previous logs in the register this year.

08/01/2007 I hiked up Coalpit Gulch with Matt and Grizz to the top of North Thunder, we continued on the Hematoma route to South Thunder, Bighorn and Lone peak.
09/19/2008 Climbed North Thunder with Matt. We came down Thunder Bowl into Bells Canyon, which was beautiful this time of year.

Made the climb with Greg(gjagiels.) Slick, slimy logs and rocks in the creek with stinging nettles and thick brush everywhere else made the bushwacking pretty intense above the waterfalls. The route before and after that section, however, was great! Worth doing once. Continued on to S. Thunder and descended Bells.

Coalpit Gulch up, Bell's down. Climbed striaght up the second waterfall which was scary and stupid. The rest of the climb was beautiful and steep. Lot's of solitude. Was sitting reading the summit register when I heard a high pitched sqeak very close by. At first I thought it was a bird and discounted it, but then it came again I looked over the summit boulder and was face to face (within 2 feet) of a baby mountain goat. I was as startled as it was and fumbled for my camera, but was to slow before it bounded out of view. Surprised to see the register account of the solo adventure up Perla's and then over the northwest ridge. Scary looking.

Coalpit Gulch is one of the gems of the Wasatch! What an incredible place. The gulch was bursting with waterfalls, trees, flowers, moss, and even wild raspberries. Once the gulch opens up, there is quite a bit of bushwacking, and the gulch is choaked with dead trees from avalanches. This creates slow, tedius hiking, but the scenery keeps it interesting. Once you pass the bushwacking and get back on the open boulder fields you can pick up the pace all the way to the top.

Glad to see a separate page for this very separate peak. I placed a pvc tube and summit register here some years ago (1997?) and brought down the old one, which was in bad shape and in real danger of disappearing altogether. I have that register (and various business cards and scraps of paper) in my possession and will share it with anyone interested. It has a few entries from the 1950's and 1960's.

Gristle (Joe Bullough) and I bagged this baby one more time on the penultimate day of 2006! What a day! Joe says a TR will follow.

On March 6, 2008, (via Bells Canyon)three of us attempted the peak by climbing the steep slopes east of the meadow. Arduous, tedious, tough. Attaining the summit ridge 3/4 mile north of the peak we made it within 200 yards of the summit before getting cliffed out by a small but dangerous precipitous dip in the summit ridge. It took us 6+45 to reach that point, so that wasn't too bad considering we had to break trail beginning at the spring crossing way down low! A winter attempt of this peak is a test of stamina, endurance, toughness and grit. On 3-11-08 five of us returned to "conquer" No. Thunder. And that we did. 5+25 to the snowy summit. Bluebird day. Awesome beyond description. My 3rd time at the actual summit. On 7-08-08 we began what mountaingoat calls the Beat-Up hike in the Sam Thomas Gulch, topped out on No. Thunder 5+45 and continued to So. Thunder, Chipman Peak and lastly Pfeifferhorn before exiting the nearly 15 hour day through Red Pine. Whew!!! 5th summit on 3-7-09 with Dave. 6+30 up, 3+40 down. Tough but satisfying. Ideal snow conditions but west wind and intermittent cloudy conditions all day. #6 9-22-09 Good way to celebrate the autumnal equinox, via Coalpit Gulch. #7 11-3-09 With Dave via the "snow" route; tough going but satisfying 12-hour day. #8 4-24-10 W/ Dave, Walt, Jake & Christine via Maybird Gulch & Hogum Fork. 5+50 to corniced summit. 2+45 down to Bells Canyon TH. Beautiful day: sun, no wind, good snow. #9 1-8-11 w/ Dave. Serious trailbreaking above the the meadow but excellent snow. Very cold on top. 5+45 up, 3+08 down. From Bells Canyon TH on 9800 S. #10 5-14-11 W/ Dave via the Hypodermic Needle couloir from Hogum Cirque. One steep mama. #11 12-09-11 Sehr schwer - lang Zeit. #12 4-3-12 W/ Dave. 5+23 up, 4+10 down via Bells Canyon. Beautiful day in spite of low snow totals. The lower portion of the trail had been trashed by an unknown group of unprepared people... #13 5-8-12 W/ Dave via the Hypodeemic Nerdle. Gorgeous day, fine snow as far as it went into Bells Canyon (upper meadow and that was about it!). #14 4-30-13 Checked out the route solo and found good snow from the plateau up. #15 5-4-13 With members of WMC on a near-perfect day. Excellent snow conditions and pleasant no-wind conditions on top. That doesn't happen very often on North Thunder but it did for us. Sometimes we get lucky, don't we? #16 3-15-14 Beware the Ides of March. Cold north winds and near zero viz at times but Dave & I made it with the aid of micro-spikes, snowshoes and crampons in 7+ hrs. #17 5-3-14 WMC hike. Very sloppy snow but skirted 4 big wet slides above Thunder Bowl to reach the windy summit. Eine wichtige Teilnehmerin war leider abwesend-IVD. #18 2-26-16 W/ Dave and Lana. Less-than-ideal snow everywhere. 7+28 up, 4+56 down. Started and finished in the dark. But zero wind on the summit! #19 5-13-17 W/ Dave A. Poor snow conditions all day. 7+16 up, 4+16 down. Zero viz at top, quite windy and cold for this date.

Early 1990's. North Thunder may be the toughest peak in the Wasatch and it is visited less than South Thunder (which isn't visited that often). Thunder Mountain is a real gem. Good snow climbs are on the north face too.

Climbed N Thunder Mtn first by cutting over to Thunder Mtn Bowl from the upper reservoir. I then followed the ridgeline (class 3, with some exposure) to S Thunder before descending Bells Canyon. Both summits had very nice registers on top.
